Additive Masterbatch Plast Slip

Each type of additive masterbatch has some special properties to improve the end plastic product.

SLIP ADDITIVE

Prevents sliding over itself or with equipment.

Slip additives are products which can be added to polymers to
control friction. They are added directly into the polymer during the
extrusion process and migrate to the surface as the polymer cools,
allowing a solid lubricating layer to form.

They can be used in Polymer film structures and plastic packaging to improve polymer processing and in-use properties and are a practical requirement for both the manufacturer and end-product consumer.

Role of Slip additive during Extrusion process

Slip additive are used to reduce friction between flims and extruder as it improves movement through extrusion lines and downstream packaging operations thereby enhancing processing / end applications. Initially, the slip additive is homogeneously dispersed in the film , its surface concentration is low (Fig : Phase A) and the Coefficient Of Friction (COF) is high. Due to the limited compatibility with the organic substrate, the slip additive migrates to the surface, thus the concentration on the film surface increases (Fig : Phase B) and the COF decreases. At equilibrium (Fig : Phase C), a continuous coating of at least one layer of slip additive molecules is formed on the film surface and the COF reaches its minimum value. The two major performance criteria are the migration speed to the surface (time until slip effect occurs) and the slip effect achievable (minimum COF). These two criteria are determined by:

How it Works?

Slip or surface friction, expressed as Coefficient of Friction or CoF, measures the interaction between two polymer surfaces, or, between the polymer surface and extruder. There are several factors affecting the development of friction such as :

Polymer type
Process temperature and type
Film gauge and structure
Other present additives

Effects of slip additives

Traditional organic slip additives are based on unsaturated fatty acid amides. These primary amides, which have low molecular weights, migrate rapidly through polyolefin films after extrusion and appear on the surface of the film to lower the COF. These additives are also characterized by exudation – the formation of a gel-like layer that can transfer to other film surfaces, lead to haze and affect printing operations.

Know more

Unlike these organic slip additives, silicone technologies have higher molecular weights, so they move to the surface of the film more slowly. Importantly, they provide some anchoring to the resin matrix at the surface to deliver stable COF reduction, and will not cause exudation.
Our newest silicone solutions are designed to deliver improved anchoring and are suitable for both BOPP and cast films used in bags, wrappers, packages and pouches. Some can be used in sequential and simultaneous BOPP processing.
With growing trends towards faster production rates for cost reduction with eye-catching graphics in flexible packaging industry , both depend upon the properties of advanced slip agents, which are used to reduce the coefficient of friction (COF) in bi-axially oriented polypropylene (BOPP) film. Slip agents / additives, overcome the film’s natural tackiness, enabling it to move smoothly through high-speed converting and packaging equipment.

Significant advantages of Plast Slip

Ease of Processing

Slip additives make film production easier, by preventing layers of film sticking together or sliding over each other.Reduced surface friction with stable and consistent blown film manufacturing process.

Smoothness in substitute

To maintain cost advantage in the face of volatile polymer prices and stiff competition, converters and packaging producers need new strategies like down-gauging the film, Slip additives facilitates the same to improve productivity.

Cost Optimization

New generation Silicone based Slip additives keeps haze in transparent BOPP film to a level below 2% to preserve the clarity of transparent films unlike traditional ones which can cause hazing of the film, which affects printing precision , the intensity of colors and effects.

Whats New?

These silicone slip additives also help keep costs down through their effectiveness at very low loadings of 2 wt% to 5 wt%. Further, they are typically added only to the outer layer of the film. Also it helps to reduce COF to a level of 0.2-0.3 to help ensure rapid processing and avoid film rupture or deformation that causes scrap.

Value Addition

It maintains stable slip performance over time and under high temperature conditions. Prevents die build up that causes interruptions for cleaning.
